Genki uses a Pink Suezo as his avatar monster in the video game championship that he wins on Earth. It has a very powerful "Bite" attack that is labeled as "Eat" for some reason.

In flashback in Episode 8, we see that Holly's Grandfather had a Pink Suezo as a housekeeper, and she played a very maternal role in the lives of both Holly and Suezo after Holly's mother died. She was killed in Naga's raid on their village, though she fought valiantly. Interestingly enough, she always keeps the wings on the sides of her head rolled up into what looks like pigtails.
